This introductory text describes the principles of invariant measurement, how invariant measurement can be achieved with Rasch models, and how to use invariant measurement to solve measurement problems in the social, behavioral, and health sciences. Rasch models are used throughout but a comparison of Rasch models to other item response theory (IRT) models is also provided.
Written with students in mind, the manuscript was class tested to help maximize accessibility. Chapters open with an introduction and close with a summary and discussion. Numerous examples and exercises demonstrate the main issues addressed in each chapter. Key terms are defined when first introduced and in an end-of-text glossary. All of the book’s analyses were conducted with the Facets program. The data sets used in the book, sample syntax files for running the Facets program, Excel files for creating item and person response functions, links to related websites, and other material are available at www.GeorgeEngelhard.com.
Highlights include:
A strong philosophical and methodological approach to measurement in the human sciences
Demonstrations of how measurement problems can be addressed using invariant measurement
Practical illustrations of how to create and evaluate scales using invariant measurement
A history of measurement based on test-score and scaling traditions
Previously unpublished work in analyzing rating data, the detection and measurement of rater errors, and the evaluation of rater accuracy
A review of estimation methods, model-data fit, indices used to evaluate the quality of rater-mediated assessments, rater error and bias, and rater accuracy.
Intended as a supplementary text for graduate or advanced undergraduate courses on measurement or test theory, item response theory, scaling theory, psychometrics, advanced measurement techniques, research methods, or evaluation research taught in education, psychology, and the social and health sciences, the book also appeals to practitioners and researchers in these fields who develop or use scales and instruments. Only a basic mathematical level is required including a basic course in statistic.

Store description
Equipment for Living is a socially conscious bookstore located in Aliquippa, Pennsylvania. More than just a retail business, we define ourselves as "a business with a conscience" - committed to fostering community development, meaningful employment, and urban revitalization in Western Pennsylvania. OUR MISSION: Equipment for Living operates on the belief that responsible entrepreneurship can be a powerful force for positive change. We provide valuable retail services while creating meaningful work opportunities that serve as sites of training and mentoring. Our Youth Employment Initiative specifically targets local residents aged 16-25, offering employment, skill development, and guidance during the critical transition from youth to adulthood. We measure success not just in profits, but in empowering our employees to pursue their career aspirations and life goals - even when that means moving on to other opportunities. OUR STORY: Founded in 2008 and opening our physical storefront in 2012 after extensive community-led renovations, Equipment for Living has grown from an online book venture into a cornerstone of Aliquippa's revitalization efforts. We've deliberately chosen to establish our business in this former steel town, recognizing that true community poverty isn't just about lacking economic resources - it's about lacking opportunities, connections, education, and hope. OUR INVENTORY: Equipment for Living offers a refreshingly different retail experience from typical chain bookstores. While big-box stores stock only high-demand, profitable bestsellers in predictable arrangements, we curate a wide and constantly evolving selection that reflects the unique character of our community. Our diverse inventory includes books across all genres and eras, audiobooks, CDs, DVDs, VHS tapes, vinyl records, and video games. We embrace the philosophy that "if you only read the books that everyone else is reading, you can only think what everyone else is thinking." While we may not always have the latest bestseller in stock, we guarantee a carefully selected range of high-quality products you won't easily find elsewhere - true equipment for living a rich, thoughtful life.…
